Hot mantle plumes break the surface in the middle of a plate
Hot mantle plumes burn through the asthenosphere
Hot mantle plumes burn through the lithosphere
Hot mantle plumes break between two plates
2
How many continents are there today?
Eight
Five
Six
Seven
3
What is a tectonic plate?
A slab of solid rock, made ofcontinent and ocean lithosphere
A slab of solid rock, made of oceanic lithosphere
A slab of solid rock, made of continental lithosphere
A slab of the mesosphere that floats on the lithosphere
4
Look at the picture of Earth's layers. Which of the following is a problem with this model?
There should be only two layers.
Layer A should be thicker than layer B.
Each layer should have the same thickness.
Layer B should be thicker than layer C.
5
What type of boundary is this?
Divergent
None of these
Transform
Convergent
6
Where do earthquakes occur?
In the mantle
On the edges of mountain ranges
In the center of tectonic plates
Along tectonic plate edges and faults
7
What type of boundary is this?
Divergent
Convergent
Transform
8
The theory of plate tectonics states what?
The tectonic plates float on the Earth's crust.
The tectonic plates float on the outer core.
The Earth's crust sits on top of the mesosphere.
The lithosph is made of plates that float on the asthnosph.
9
When an oceanic crust meets a continental crust, what occurs?
Ocean crust moves under the continent crust making volcanoes
Both crusts are subducteddown into the mantle
The crusts converge making fold mountains like the Himalayas
Ocean crust moves over the continent crust making volcanoes
10
The Indian Plate converges with the Eurasian Plate. When this happened, what was formed?
Rift Valley
Folded Mountains
Volcanoes
Ocean Basin
11
Shown is a picture of sea-floor spreading. How are the ocean crusts moving?
Diverging
No Movement
Converging
Sliding
12
What is the relationship between the mantle, lithosphere and asthenosphere?
The mantle is part of the lithosphere but not asthenosphere
Asthenosphere is part of the mantle below the lithosphere
The three layers are completely separate.
The mantle is part of the asthenosphere but not lithosphere
13
The large plates move across the surface of the Earth by what process
Convection
Conduction
Condensation
Radiation
14
The San Andreas Fault is known as an active earthquake area. What type of boundary is it?
Diverging
Sea Floor Spreading
Converging
Transform
15
What is the Ring of Fire around the Pacific Ocean?
A string of earthquakes around the edges of the ocean
Area where large #'s of earthquakes/volcanic eruptions occur
A string of volcano eruptions around the edges of the ocean
16
What type of boundary is this?
Convergent
Divergent
Transform
17
What is the "engine" that moves the plates?
Radiation

Four
Five
Two
Three
19
How are mountains formed?
Mountains are formed at divergent boundaries.
Oceanic crust collides with more oceanic crust.
Oceanic crust collides with continental crust.
Continental crust collides with continental crust.
20

Plate Tectonics
Volcanic Island Arc
Folded Mountains
Sea Floor Spreading
